单选题America put more people in prison in the 1990s than in any decade in its history. That started a debate over the wisdom of spending billions of dollars to keep nearly 2 million people locked up. According to statistics, the United States ends 1999 with 1983084 men and women in prisons. That shows an increase of nearly 840,000 prisoners during the 1990s and makes the United States the country with the highest prisoner population in the world. With the cost of housing a prisoner at about ＄20,000 a year the cost in 1999 for keeping all these prisoners behind bars is about ＄ 39 billion. Some experts argue that the money is well spent, saying the cost of keeping prisoners behind bars doesn't seem much in comparison in the 1990s coincided with (与……相一致) a steady drop in the US crime rates. It is reported that serious crime has decreased for seven years in a row. "There are noticeable number of people who don't do crimes because they don't want to go to prison," they say.

单选题The domestic economy in the United States expanded in a remarkably vigorous and steady fashion. The revival in consumer confidence was reflected in the higher proportion of incomes spent for goods and services and the marked increase in consumer willingness to take on installment debt. A parallel strengthening in business psychology was manifested in a stepped-up rate of plant and equipment spending and a gradual pickup in expenses for inventory. Confidence in the economy was also reflected in the strength of the stock market and in the stability of the bond market. For the year as a whole, consumer and business sentiment benefited from the ease in East-West tensions. The bases of the business expansion were to be found mainly in the stimulative monetary and fiscal policies that had been pursued. Moreover, the restoration of sounder liquidity positions and tighter management control of production efficiency had also helped lay the groundwork for a strong expansion. In addition, the economic policy moves made by the President had served to renew optimism on the business outlook while boosting hopes that inflation would be brought under more effective control. Finally, of course, the economy was able to grow as vigorously as it did because sufficient leeway existed in terms of idle men and machines. The United States balance of payments deficit declined sharply. Nevertheless, by any other test, the deficit remained very large, and there was actually a substantial deterioration in our trade account to a sizable deficit, almost two-thirds of which was with Japan. While the overall trade performance proved disappointing, there are still good reasons for expecting the delayed impact of devaluation to produce in time a significant strengthening in our trade picture. Given the size of the Japanese component of our trade deficit, however, the outcome will depend importantly on the extent of the corrective measures undertaken by Japan. Also important will be our own efforts in the United States to fashion internal policies consistent with an improvement in our external balance. The underlying task of public policy for the year ahead--and indeed for the longer run-- remained a familiar one.- to strike the right balance between encouraging healthy economic growth and avoiding inflationary pressures. With the economy showing sustained and vigorous growth, and with the currency crisis highlighting the need to improve our competitive posture internationally, the emphasis seemed to be shifting to the problem of inflation. The Phase Three program of wage and price restraint can contribute to reducing inflation. Unless productivity growth is unexpectedly large, however, the expansion of real output must eventually begin to slow down to the economy"s larger run growth potential if generalized demand pressures on prices are to be avoided.

单选题When we eat may be just as important as what we eat. A new study shows that mice that eat when they should be sleeping gain more weight than mice that eat at normal hours. Another study sheds light on why we pack on the pounds in the first place. Whether these studies translate into therapies that help humans beat obesity remains to be seen, but they give scientists clues about the myriad factors that they must take into account. Observations of overnight workers have shown that eating at night disrupts metabolism and the hormones that signal we"re sated. But no one had done controlled studies on this connection until now. Biologist Fred Turek of Northwestern University in Evanston, Illinois, and graduate student Deanna Arble examined the link between a high-fat diet and what time of day mice eat. A control group of six nocturnal mice ate their pellets (60% fat by calories, mostly lard) during the night. Another group of six ate the same meal during the day, Turek says, which disrupts their circadian rhythm—the body"s normal 24-hour cycle. After 6 weeks, the off-schedule mice weighed almost 20% more than the controls, Turek and Arble report today in Obesity, supporting the idea that consuming calories when you should be sleeping is harmful. Turek and Arble acknowledge that the disrupted mice ate a tad more and were a tad more sluggish, but the differences could not account for all of the weight gain. In the second study, a different team of researchers investigated the link between weight and the immune system. Hundreds of genes seem to affect the accumulation of fat, but one that helps protect us from infection might help us lose weight with little effort, biochemist Alan Saltiel of the University of Michigan, Ann Arbor, and colleagues suggest today in Cell. The researchers tested me weight-adding abilities of a protein called IKK ∈ , which is linked with obesity, diabetes, and chronic, low-level inflammation. For 3 months, the team fed six mice missing IKK ∈ genes a diet of high-fat chow. Because IKKE"s main job is immune defense, Saltiel"s team didn"t expect to find weight differences between knockout mice and controls. But the knockout mice did gain significantly less. Best of all, the girth the animals did add was less harmful to their overall health. "The knockout mice don"t gain as much weight but also don"t get diabetes, don"t get insulin resistance, and don"t get accumulation of lipids on the liver," Saltiel says, all of which contribute to the suite of health problems associated with being overweight. Saltiel calls IKK e " an especially appealing drug target for the treatment of metabolic disease. " Tom Maniatis, a molecular biologist at Harvard University praises the study but remains skeptical about any drug that would inhibit IKK ∈ . He helped develop the mice used in the experiment and notes that they are vulnerable to the flu. He suspects that suppressing IKK ∈ may help people with diabetes or obesity, "but the first time the swine flu comes along, that"s it. Researchers are also enthusiastic about the circadian rhythm paper Frank Scheet, a neuroscientist at Harvard who studies sleep, was struck that " you could see something happening [ to the disrupted mice] in the first week already. That"s consistent with human studies where we found changes in just 3 days. " Together, the papers suggest that there"s no simple answer to why people gain weight. Says Turek, "It"s clearly not just calories in versus calories out. "

单选题Giving psychologists the option to become trained prescribers may create a division among psychologists whereby some will be able to prescribe and others will not. As a result, major discord could emerge. It is possible that psychologists with the fight to prescribe may consider themselves superior to those without the right. If gaining prescription privileges would lead to broader third party payments or full hospital privileges for those qualified to prescribe, psychologists unable to do so may feel that they have been accorded second class status in their profession. The debate, thus far, has focused on the training necessary to grant psychologists prescription privileges. Although this matter is important, of more basic concern are treatment implications and the future role of psychologists. Prescription privileges could move psychologists closer to a medical model and further away from their historical goal. Psychology began in the late 19th century as an application for psychological techniques. Its focus has been on assessment, behavioral interventions, Consuhation, and applied research. Before the widespread use of psychotropic medications, psychiatry emphasized the practice of psychotherapy. Gradually, psychiatry moved toward increased reliance on drugs and away from psychotherapy. It is possible, over time, that psychologists, like psychiatrists, could become more influenced by the use of medication. Despite the argument that prescription privileges significantly may alter traditional psychotherapeutic implications, some psychologists strongly feel that they would be looked upon more favorably, gain prestige, and increase their caseload if they could have the same status of prescribing medication as psychiatrists do. Does this mean that a lack of prescription privileges promotes the image of psychology as an inferior profession to psychiatry? Contrary to this argument is the fact that psychologists are delivering more outpatient mental health care than any other group of providers. Whatever some psychologists may perceive as a therapeutic drawback because they are unable to offer prescriptions for psychotropic medications apparently is not recognized by the general public. Psychologists may have flourished because they have offered a clear and distinct service from psychiatry. The use of medication may send a message to patients that may interfere with personal change and growth. Medications can undercut psychotherapy efforts by implying that benefits come from external agents, not from one's own efforts at change and growth. A large portion of the population prefers the non-medication orientation of psychology. If psychologists began prescribing medications, many of their patients seeking alternative treatment might turn to social workers or other non-medical therapists. There is little question that psychologists' prescription privileges could have profound effects on the future direction of their profession.
